DFAM Thing

Feel free to email me at serendipity.synth@gmail.com with any questions or comments, or if you are interested in obtaining a DFAM Thing.
Standalone Eurorack

The DFAM Thing is a device that adds significant capabilities to the DFAM (or Edge) sequencer, such as:

The Eurorack version supports many of these capabilities in an 8HP module, but with V/Oct CV support in place of MIDI.

The DFAM Thing Quick Start guide can be found here.

The DFAM Thing Firmware Update guide can be found here.

Major Update

The DFAM-Thing (in future simply the D-Thing since it also supports the Behringer Edge) is now available in a folded aluminium case.

Similarly, the Semi-Modular Thing (henceforth the M-Thing) is ready for sale. See below for details.

Update Apr 29, 2023: I now have a dedicated email address (serendipity.synth@gmail.com) for communication regarding the DFAM Thing or any of my other devices.

Update Mar 9, 2024: New firmware (v1.4) is available for both versions of the D-Thing. For the Standalone device, there is now support for Tap Tempo when using the internal clock. For the Eurorack module, improvements have been made to the timing when running in CV mode.

Update Apr 21, 2024: Firmware v1.5 is now ready and is available for download. With this firmware, all versions have full compatibility with the Behringer Edge. In addition, this update brings some major new capabilities to the Standalone D-Thing: Multistep (ability to repeat any step up to 8 times), Swing beat, and Microtiming (move beats off the grid by up to 33% ahead or behind). See below for more detail.

Some other items of interest:


The following video briefly shows the basic functions (using the internal clock).

Eurorack Demo

The Eurorack version is an 8HP module, with V/Oct CV support in place of MIDI, and a dedicated encoder for selecting the number of steps in place of the 8 buttons of the standalone version. Please note that it also does not support functions that rely heavily on the 8 numbered buttons — specifically clock multiply and divide, tap tempo, multistep, microtiming, or allow entry of a custom pattern.

New Features in Firmware 1.5

Swing and Microtiming

Swing timing can be selected using the Control encoder, and is simply toggled on and off. When on, every second step is delayed by 1/3 of a beat.

Microtiming has its own submenu for programming and control. When Microtiming is selected, you can use the submenu to:

Here is a demo of these features using the Behringer Edge.


Multistep also has its own submenu for programming and control. When Multistep is selected, you can use the submenu to:

The other options behave in the same way as for Microtiming.

Here is a demo of these features using the Behringer Edge.


Here is a detailed review of the original version of the DFAM Thing by Melbourne artist Bribery.


Integrating the DFAM Thing with the DFAM and other gear is via two CV outputs, two CV inputs and a MIDI input. These are all on the right hand side of the device so as to not interfere with operating the controls.





Press to start or stop the sequencer. Tap while running to reset to step 1.


An encoder for selecting modes and other funtions. Rotate to select, click to apply.


A potentiometer for setting the speed of the internal clock.


A switch for selecting between internal, external and MIDI clocking of the steps.

Buttons 1-8

8 buttons for setting the sequence length in the standard modes, but also for manually playing particular steps, defining a custom sequence, or setting clock multiply/divide factors.


A small button for rebooting the controller.


A trimmer pot accessible from the rear for adjusting the LCD contrast.

Sequencer modes (patterns)

The number of steps (other than for a custom sequence) can be set to anything from 1 to 8 by clicking the corresponding numbered button. The length chosen is displayed at the top right of the screen.

Other modes

MIDI Control

New in firmware 1.3 of the standalone DFAM Thing is support for MIDI CCs.

What’s that little switch?

Unfortunately the MIDI circuit interferes with programming the Nano via USB, so the small switch is there to disconnect the MIDI circuit when programming the chip. (It also possible of course to remove the chip from the board in order to program it.)

If you accidentally flick the switch (so the actuator is closest to the Nano) then MIDI will not function. This is the first thing to check should MIDI stop working.

The Semi-Modular Thing

The Semi-Modular Thing, in future simply the M-Thing, is a small device designed to work alongside a semi-modular synth (such as the Moog Mother-32, or Arturia Minibrute) and provide additional utilities, modulation sources, and mixing. Now available in a folded aluminium case.

M-Thing Specifications

  • Digital LFO (Uses the Electric Druid TAPLFO chip)

    • 0.5Hz to 20Hz (roughly)
    • 16 waveforms, organised in 2 sets of 8
    • 1x, 2x and 4x speed options using a toggle switch
    • clock out
    • external sync (within the supported frequency range)
    • normal and inverted outputs available simultaneously
    • uni-polar (0 to 5V) or bipolar (-5V to 5V) output
  • White Noise

  • Sample & Hold

    • signal input normalled to white noise
    • clocked by the LFO
  • Crossfader

    • 2 arbitrary inputs
    • default fades between a low-pass (brown-ish) noise to a high-pass (blue-ish) nosie
  • Sub-oscillator

    • Square wave output at -1 or -2 octaves
    • Optional mixed output (full original signal with adjustable sub level)
  • Attenuverters/mixer

    • 3 attenuverters
    • switch controls inclusion in a mixed output
    • each is normalled to 5V (so it gives -5V to 5V), the LFO and the S&H respectively
    • usual scale is from -1 to +1 times the input, but jumpers on the board can switch them to -1 to +2 times (up to 10V).
  • Multiples

    • 2 three way multiples

Here is a step-by-step demonstration of how the M-Thing can add a bit extra to a Mother 32, before playing along with a D-Thing/DFAM pair, then a Matriarch, and finally a Roland System 100.

This demo of the prototype examines the individual functions in more detail.
